Setting the standard Our initial line of medium voltage resistive voltage divider based voltage and current sensors, conveniently embedded into post insulators, have even become referred to as Lindsey sensors. Hundreds of thousands have been installed over the past 25 years for good reasons: Accurate to 1%, excellent harmonic response, and no phase shift on voltage and current provide the confidence needed for today’s Volt and VAR control applicationsA mean time between failures (MTBF) exceeding 10,000 years means true install-and-forget reliabilityConstruction that meets all the electrical and mechanical requirements of post insulators provides endless installation options.
